Geometry Toolbox: A Website for Measurement
Summary : Digitalizing Geometry Tools!
Geometry Toolbox provides users with access to a digital protractor, ruler, and compass. After launching the website, users can select the tool they wish to use from the right side menu by clicking it. The tool then appears on their workspace. At this point, users can position the tools around the screen by clicking on one of the tools and dragging it. If users wish to write on the screen, they can do so by clicking on the “Pencil” or “Pen” from the menu, choosing an ink color from the bottom menu, and then writing with it. The difference between the two writing utensils is that the “Pencil” will only make straight marks and the “Pen” is completely freehand. After making a mark on the workspace, users can click the “Undo” button to remove the last mark they made. If they wish to remove all their markings, they will need to click the “Clear” button.
Please Note: Users cannot save the work they made while using this website. If they do wish to save it, users will need to take a screenshot of their work before leaving the website or clearing the screen.
- When learning about the compass or the protractor, teachers can have students load this website and practice making angles and circles. To do so, teachers can ask students to make different sized angles (e.g., 37 degrees, 48 degrees, etc.) with the protractor or make a circle with different sized diameters (e.g., 2 cm diameter, 3 cm diameter, etc.). As students create these angles and circles, teachers can make sweeps of the room to support students and provide assistance when needed.
- Teachers can project a word problem for geometry and students can solve it using the tools in this website. After they solve it, teachers can have students take a screenshot of their work and solution and then email that to them.
- When solving practice problems that requires the use of a protractor and/or compass, teachers can have students use this website.
- As a friendly class competition, teachers can challenge their students to see who can create the most sophisticated, intricate drawing using only the compass tool and inks provided in this website. When finished, students can take a screenshot of their work and email it to their teacher. The teacher can then display the different works throughout the classroom and students can vote for their favorite. Teachers can add a twist to this activity by: (1) Limiting the amount of circles that can appear on the work, and (2) Requiring students to write a justification explaining why they voted for the drawing they selected.
